Winter in southern Aus is giant cuttle mating season. These normally secretive relatives of squid and octopus become all outgoing and inquisitive.

They will often follow divers around and even occasionally come in for a hand shake, like in this video.

I was shooting stills at the time then quickly switched to video when the cuttle showed interest. With a bit more time i would have done a manual white balance and used -1.0 ev in Aperture priority for better colour and exposure.

I don't hesitate to use bounced flash when photographing above water but it had never considered it underwater.

On a recent dive on the ex HMAS Canberra frigate, in less than perfect vis, I tried a few shots with the strobe pointing up at the ceiling of the wheelhouse. The results were a great improvement over direct flash which produced bad backscatter.

Top image is direct flash, single strobe.
Lower image is the bounced flash version.
